SPECIFICATION forming part of Letters Patent No. 716,7 21, dated December 23, 1902.

Application fled November 14, 1901. Serial No. 82,204. (No model.)

To @ZZ whom, t may concern:

Be it known that I, CLARENCE E. YKnLLvg'a citizen of the United States, and a resident of Anderson, in the county of Madison and State of Indiana, have`invented a new and lmproved Speed-Indicator-Operating Means, of which the following is a full, clear, and eXact description.

This invention relates to a means for operating a speed-indicator. lt maybe used to indicate the'distance traveled bya vehicle in a stated time, or it may be fitted to show the number of revolutions per minute of a turning part.

This specification, is a specific description of oneform of theinvention, while the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure lis a face view of the invention with parts broken away. Fig. 2 is a section on the line 2 2 of Fig. l. Fig. 3 is an elevational view showing the cover-plate removed, and Fig. t is a fragmentary section on the line 4 Y 4 of Fig. l.

a indicates a rotary shaft, to which my invention is here shown as applied and from which it derives its movement. a casing keyed to turn with the shaft. The casing Z9 has a cover-plate c, formed with a rabbet-groove on its periphery, in which groove are engaged the heads of screws b, fastened to the casing l), thus holding the cover-plate c on the casing, so thatit may be turned around the axis of the shaft a independentl \T of the casing for the purpose of adjusting the plate, as will be fully described hereinafter. The casing o has a hub b2, which fits on the shaft a, and d indicates a disk which fits loosely around this hub h2 outside of the cover-plate c. The disk CZ has pins d attached rigidly thereto, such pins passing through the coverplate c into the casing l). It will be Observed, therefore, that the adjustment of the cover c carries with it a like movement of the disk d and pins d.

Fastened to or formed integral with theV back wall of the casing b and located within said casing are radial guideways e. In these h indicates.

guideways are respectively arranged spherical weights e', which are movable through the guideways to and from the axis of the shaft a. These weights c' are adapted to be actuated by centrifugal force, and the guideways e are longitudinally slotted to receive loosely the arms f of segmentalcams f. The cams fare mounted to turn on pins f2, carried by the cover-plate c in parallelism with the shaft a, and the Working faces f4 of the cams (see Fig. 3) are disposed spirally around the axes of the pins f2. S [wing-pressed plungers f3 are carried by the peripheral wall of the casing b radially of the shaft a and engage With the arms f', pressing the same inward. vThe pins d', which are fastened to the disk d and project loosely through the cover-plate c, respectively engage the working faces f4 of the segmental cams f. As the shaft a turns its motion acts on the spherical `weights ef, tending to throw them outward in their guideways c. The movement ofthese weights is transferred to the arms f', and the cams f [areA caused to turn around their pivotpins f2. These cams iu turning ride their working faces f4 on the pins d' and push the pins outward, these pins carrying with them the disk CZ.

g indicates a rock-shaft held in a suitable support g' and carrying an arm g2, which has a roller g3 running on the disk d. As the disk d moves in and out under the action of the varying speed of the shaft ct the shaft g is rocked, and the movement of this shaft is communicated to an indicating device, Whereby to show the exact speed at which the part c', is moved.

It will be observed that by adjusting the cover c around the axis vof the shaft c the cams f, arms f', andpins d will be moved with the cover, and the axes around which the arms f swing will beadvanced to or retracted from the respective spherical weights e. This increases or decreases the leverage of the arms, and by this means the apparatus may be adjusted to the gear of the rotary ele- IOO f rom the centrifugally-actuated part whereby yIo upon the relative adjustment of the parts of the carrier the action of the device may be regulated.
